' WINDOW CONSTRUCTION Filed July 26, 1957 f 2 Sheets-Sheet 2 States Paten WINDOW CONSTRUCTION John V. Rylander, Pasadena, Calif. AppiicationJuly 26', 1957, Serial No. 674,338 8. Claims. (Cl. 20-522) This invention relates to window construction and more particularly to a novel method of mounting window sash, storm sash or screen sash in position in a window frame which allows a highly effective window construction to be achieved because of the'thinness of the comb'ined-upper and lower sash employed.

Previously it has been contemplated that panes of glass or panes of glass having a peripheral border of metal, plastics, or the like may be used as a sash in a window. However, because of the thinness of the sash, it has been very diflicult to achieve an arrangement whereby the sash may be easily removed and replaced and whereby the sash maybe held in an adjusted position as desired. The concept of this invention lies in the provision of a novel friction holder which will hold the sash in an adjusted position and which is readily adaptable to vertically sliding sash and which may be employed for use with windows, storm sash, or screen sash as may be desired.

A further object of the invention lies in the provision of novel means including a cross bar mounted between the sash of a window which may be readily and easily removed along the upper and lower sash to be removed as desired.

Another object of the present invention lies in the provision of a novel window construction employing a cross bar which may be readily pivoted out of the way to permit movement of the vertically sliding sash or the like.

Another object of the present invention lies in the provision of a window construction employing sash which are relatively thinso as to enable several layers of the storm windows to be employed in locations where there are severe weather conditions.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this window construction, preferred arrangements of parts being shown in the accompanying drawings, by way of example only, wherein:

' Figure 11 is a partial perspective view of aform'of window pane having a peripheral border.

With continuing reference to the accompanyingdrawings wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 generally designates a window frame constructed in accordance with the concepts of the present invention and including vertical portions as wellas horizontal portions which are provided with grooves as at 12 for reception of the sash employed in the invention. As :can be bestseen in Figure3, the grooves may be:further represented by reference numeral.14.- for the lower sash 16 of the window together with groove 18 forthe upper sash 20 as well as the groove 12 for the lower storm sash 22 and a groove not clearlyvisible, but indicated at 24 for the upper, storm sash 26.

The construction of the invention as applies to the window sash 16 and 20 will befirst considered.

The frame 10 isprovided witharecess-28 communicating with the. respective grooves in which resilient springs 30 and 32- are mountedfor protecting the corners of the sash. In order to resiliently hold the sash in position such as when the lower sash 16 is raised, there is provided thefriction holder as indicated at 34. The construction of the friction, holder can be best seen in Figures 4 and 5. and includesxa holder frame'36' of any suitable shapesecured byfasteners as at 38 to the window framelO. Incorporated'in the invention is a tension bar 40'and a slide bar 42. Bolts as at 44 and 46 forming a first set of bolts have head portions engaging the slide bar-42 slidably extendingthrough the tension bar 40 and are threadedlyyengaged as at 48 and 50 with the frame holder 36.- Coil springs 52 and 54 are disposed about the bolts 44 and 46. Another'pair of bolts 56 and 58 are threadedly engaged in the tension bar it) having thear heads engage the slide bar 42 and the ends thereof engaging the-holder frame 36. Other coil springs 6t]: and 62"are disposed about the'bolts 56 and 58; As can be readily determined, the adjustment of the bolts 44 and 46 will serve. to adjust the ultimate position of the slidebar 42 while adjustments of the bolts 56 and 58will cause the tension bar 40-to move towards or away from the slide bar 42 thus adjusting the tension on the coil springs about the bolts and such other coil springs as indicated at 70 that may be seated and extend between the tension bar 40 and the slide bar 42 as is needed to provide the force necessary to support the sash. Other type springs than coil springs may be employed.

The slide bar 42 has a cam surface as at 72 engageable by the tapered cam surface 74 ofthe slide holder 76wh'ich is of a hook shape having a hook end portion 78 engageable with theslide bar 42 and having an adjusting screw 80 for providing the limitadjustment for position ofthe slide holder 76 with respect to: the slide bar 42. Of course inzlieu. of tapering the end of the cam surface 74, the cam surface 72 may be tapered for reducing friction therebetween. A pad 84 of any suitable material such as plastic, leather or the like is provided for engagement with the sash 16. A recess or hole 88 is provided in the slide holder 76 so as to enable a nail or any other tool to be inserted therein whereby the slide holder can be easily removed.

In operation, the sash 16 may be easily raised without adversely affecting the position of the slide holder 76 due to the fact that there is sliding contact between the cam surfaces 72 and 74 which will not increase the friction between the pad 84 and the sash 16. However, downward movement of the sash 16 will be restricted due to the fact that it will force the slide holder 76 downwardly. This will serve to frictionally hold the sash 16 in an adjusted vertically raised position upon any downward movement being applied thereon. Of course, to reposition the sash 16 in a lowered position, the slide holder 76 can either be removed or temporarily loosened. Further, when it is desired to remove the sash 16 from the window frame, by simply removing the slide holder 76, the sash may be lifted into the recess 28 and easily removed from the frame.

There may, of course, be provided suitable friction holders 34 for the storm sash 22 and even for the upper storm sash 26 if such is found desirable. Further, handles as at 92 and 94 may be provided for raising the lower window sash 16 and the storm sash 22 if such is found desirable.

A cross bar 100 is disposed between the lower sash 16 and the upper sash 20. This cross bar construction can be best seen from an inspection of Figures 7 and 8 includes a pin 102 which is fixed into the cross bar as well as a pin 104 which is slidably adjustably fixed within the cross bar by means of a lock screw 106 extending through a slot 108 in the cross bar 100 and being threadedly engaged with the pin 104. The pin 102 is provided with a pivotal mounting for the cross bar 100 with respect to the window frame and likewise the pin 104 provides a pivotal mounting at the other side of the frame 100. As can be best seen in Figure 9, three plates are employed in seating the pins 102 and 104. These include an inner plate 120 provided with a slot 122 therein as well as with a pair of apertures 124 and 126 into fasteners 128 and 130 are adapted to be threadedly engaged. The fasteners 128 and 130 extend through slots 132 and 134 in an intermediate plate 136 having an aperture 138 forming a bearing for the pins as at 104. A face plate 140 is also provided and has apertures 142 and 144 which may be countersunk for reception of the heads of the fasteners 128 and 130 and also has countersunk apertures 146 and 148 through which fasteners 150 and 152 extend for holding the plate assemblies within the cavity 160 provided therefor. A slot 162 is provided in the plate 140 through which the pin 104 may adjustably extend. By use of these plates, the position of the cross bar can be readily adjusted it being noted that while the plate 140 is fixed to the frame, the ultimate position of the plate 136 which is the bearing support for the pin 104 may be adjusted thus raising and lowering the mounting position of the cross bar. A similar construction is of course provided for the pin 102. In order to lock the cross bar in a horizontal position, there is provided a locking bar 180 which is pivoted as at 182 by means of a pin 184 to the cross bar 100. The locking bar carries a detent 186 and has a handle 188. The detent is engageable with the screw head 190 adjustably mounted within a slot 192 in a plate 194 secured by a pair of fasteners 196 to the window frame inwardly spaced from the window sash thereby permitting operation only from the inside. The screw of the screw head 190 is threadedly engaged in a plate 198 held against the plate 194 by the" screw 190. Of course, the screw 190 may be adjusted by being partially threadedlyremoved from the plate 190 allowing reposition of the plate and therefore of the head 190.

When it is desired to remove the sash from the window it is merely necessary to disengage the locking bar 180 and then rotate the cross bar so as to disengage the cross bar from the sash. It is to be recognized that the cross bar 100 may be formed of any suitable shape and may have grooves as at 200 into which the upper edge of the sash 16 can extend and may be notched as at 202 for reception of the lower edge of the sash 20. Further, the sash may fit into the cross bar only tightly enough to provide a suitable seal while still permitting rotation of the cross bar.

Of course, in lieu of using the panes without any reinforcing border, a sash as indicated at 300 in Figure 11 may be employed which includes a peripheral frame 302 about the pane 304 and may have integrally formed therewith suitable handles 301 for operating the sash.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
